The 2013 Cadillac XTS isn't just a new Caddy boat, it's a legitimate competitor to ze Germans. This is the American car made to take on the S-Class, 7-Series, and A8. By the looks of it, it will do a damn good job of it too.
The XTS will channel 300 horsepower from the 3.6L V6 to either the front or all four wheels. Fuel economy isn't bad either at 17/28 for FWD models and 17/27 for AWD.
The real story here is the interior though. This thing has enough rear legroom to drag a few pro basketball players around and enough leather to keep them from complaining.
